Cubic Fe 3+ is formed by X‐irradiating LiCl:Fe crystals grown in a reactive atmosphere. The spin Hamiltonian parameters are consistent with the Fe cub 3+ center, earlier observed in AgCl and NaCl, consisting of an interstitial Fe 3+ forming a tetrahedral (FeCl 4 ) − complex, the four nearest‐neighbour cation sites being vacant. The superhyperfine structure analysis in samples containing 57 Fe enriched iron gives the hyperfine splitting 57 A = (9.4 ± 0.5) × 10 −4 cm −1 . No such center is found in KCl:Fe and RbCl:Fe crystals.
